Wait, people think this is sensitive? Must not be mouse and board FPSers. Sensitivity is fine, WAY too slow, but tolerable. What I hate is the lack of inverse controls. Makes every Unity game a flippin' chore to play.
I LOVE this, however, it does need a bit of improvement. Firstly, why does it keep erasing the last note I try to write? Last note in the final measure always seems to be replaced by a rest. Secondly, I would love to be able to use different not lengths, and I'd also love another octave. I've got some pieces I've composed (for guitar), and it would be awesome to be able to use them in the game. :)
Option of grid notation would be great. Make it easier to "compose" across sheets. A simple overlay of numbers along the top and side would be sufficient.
